Subject RE: Substring / regex on a package name?
Date Wed, 13 Oct 2004 10:35:18 GMT
Thanks Ivan, that is great...

Re: the repackage - move certainly would be a start, but I was looking
for a repackage task that would recurse from a point (ie. '.') and move
all dirs/java sources/props files etc.. into a new package structure...

Ie. From com.oldapp to com.newapp ..

But also, I would want it to rename any paths in the files (ie.
Com/oldapp to com/newapp) and any package names / import statements...

I had to write something like this last week, it is not quite generic
enough to make it an offering as an optional task as yet... but I
wondered if there was anything else out there like this....  I saw a
rename packages task on java.dev.net somewhere but it did not seem to
work..

Ben

You can use ant-contrib[1] task PropertyRegex, an
example copied directly from[2] shows that it is
possible:
    <propertyregex property="pack.name"
              input="package.ABC.name"
              regexp="package\.([^\.]*)\.name"
              select="\1"
              casesensitive="false" />
    
This will yield ABC.

Or you can using a scripting language (like
javascript) in ant to manipulate your string (but I am
not so good in it to provide sample).

There is a <move> task that can rename the packages
viewed as directories. Is this want you want>
